Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Line a large bread pan (18 in. by 25 in.) with pie crust.
Make and bake
In a large bowl, mix together the cake crumbs, sugar, lard, molasses, water or milk, eggs, flour, and baking soda until well combined.
Fold in the currants or seedless raisins.
Pour the mixture into the lined pan.
Bake in the preheated oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that sets the batter as it bakes.
- Eggs
- Bind the batter and help it set into a firm, sliceable crumb.
- Baking soda
- Reacts with the molasses to lift the batter and deepen its color.
- Molasses
- Adds sweetness, moisture, and a dark, rich flavor.
- Lard
- Adds fat that tenderizes the crumb and carries flavor.
